Assembly of folding props is fairly straight forward. The hardest part is stretching the bungy onto the button. Here is the simplest way. (click on the pictures to enlarge)

   
Thread a cord from between the blades out under the blade pivot, through the bungy loop and back out between the blades. Tuck the bungy under the wing of the hub.
   
Pull the doubled cord until you can stretch the bungy over the button (you'll need to hold the hub and blade apart slightly).
   
Slip the cord out from between the button and bungy and gently pull it out. Make sure the join in the bungy is out of the way as the blade opens and closes.
